This hook allows you to do something with the data that was entered in the form before it is changed and the form is updated.
Usage
add_filter( 'frm_pre_update_entry', 'check_if_value_changed', 10, 2 ); function check_if_value_changed( $values, $entry_id )
Parameters
- $values (array)
- $entry_id (integer)
Examples
Check If Value Has Changed
You can use the following example to check to see if a value has changed. In this specific example, if the value has not changed, an email notification will not be sent.
add_filter( 'frm_pre_update_entry', 'check_if_value_changed', 10, 2 );
function check_if_value_changed( $values, $entry_id ) {
$field_id = 125; // change 125 to the id of the field to check
$previous_value = FrmEntryMeta::get_entry_meta_by_field($entry_id, $field_id);
if ( isset( $values['item_meta'][ $field_id ] ) && $values['item_meta'][ $field_id ] == $previous_value ) {
// do something if the value did not change
add_action( 'frm_trigger_email_action', 'frm_stop_email', 1 );
}
return $values;
}
function frm_stop_email(){
remove_action( 'frm_trigger_email_action', 'FrmNotification::trigger_email', 10 );
}
Replace less than operator reference
Use this code snippet to convert every < to a < on create and update for a target field. Replace 7173 with your target field ID.
add_filter( 'frm_pre_create_entry', 'convert_encoded_lt_back' );
add_filter( 'frm_pre_update_entry', 'convert_encoded_lt_back' );
function convert_encoded_lt_back( $values ) {
$target_field_id = 7173; //Change 7173 to the ID of your target field.
if ( ! empty( $values['item_meta'][ $target_field_id ] ) ) {
$values['item_meta'][ $target_field_id ] = str_replace(
'<',
'<',
$values['item_meta'][ $target_field_id ]
);
$_POST['item_meta'][ $target_field_id ] = $values['item_meta'][ $target_field_id ];
}
return $values;
}
